Summary

  1. 1.

    A law of the change in the differential molar free energy of sorption of n-alkanes as a function of the length of the chain, the polarity of the stationary phase (SP), and the temperature of analysis has been found.

  2. 2.

    The energy contribution of a methylene unit of an n-alkane changes hyperbolically with the chain length, rising to the first members of the series. The greatest contribution to the free energy of sorption of an n-alkane is made by the α-methylene unit, and then by the β- and γ-methylene units.

  3. 3.

    An equation has been proposed which permits the calculation of\(\Delta G_{n,av}^{CH_2 }\), the coefficients of which depend on the SP and the temperature of analysis. The energy contribution of each methylene unit in the interval studied depends linearly on the temperature.
